on the front buffer. beam, and the casing 1 is, in practice, insulated from the metallic parts of the locomotive for` a purpose that will later appear. I

, f The casing 1 is providedwith bearings 2 in which the valve holding shaft 3 is located. They shaft 3 projects.- into the valve mecha -nism 2O (which valve mechanism maybe of any approved type such, for instance, asis shown in. the application filed by JeanF.

In addition to the foregoing projections, the cam 4 is provided with ank arm 7 that has aholding notch 8 to receive the spring latch 11 that holds the-shaft from accidental'displacement, the arm 7 having notch 8, the resiliency of the latch will con 4vtinue the rotation ofthe shaftuntil the `.latch linger engages a second projection 9 to arrest the openingmovement imparted by the spring latch 11.

12 .is a lug carried by the/lever 7 to,cop. crate with the projectionslT-l on the head ofthe resetting .trod 13, the resetting .rodl f passingthrough a bearing 14 with which it has a pin and slotconnection 15. IA spring 16 presses the resetting rod to the position shown -in Fig. 1. The resetting rod 1 3 is a manual resetting-rod that is adapted tobe connected up in such manner that the engineer by pulling the rod l13V can reset the shaft 3. rIhe head of the resetting rod 13 is also guided in a dove-tail slot 19 in a portion of the casing (see Fig. 3).

Asbefore stated, the valve 20 may be of any lapproved construction, and we have therefore simply diagrammatically illust-rated t1` e same in Fig. 3 ofthe drawings, as

the construction of the valve. per se, forms no part of the present invention.

' 2l is the plunger guide in which the l same yieldable.

plunger 22 isoperatve. The plunger 22 has a stem 23 which is flattened at 24 to pass vlthrough an Aaperture of'simila'r cross section inthe cap 61 to prevent swiveling of the' plunger, and to. the upper endy of the plungei, a rigid head 42 is` secured as also Will y of the bolts, and the bolts-are held down by a plate 28 ythat is engaged by the spring. 29 that serves to lower the plunger and tends `to hold it down. The lower or shoe section of the plunger includes al plunger engaging' part 30, a shoe proper 34 and a connecting .neck'33, the plunger engagingpart- 30 being bored at 31 to permit passage-of the bolts 2G and the portion 30 is secured in place by nuts 32.

i The joint between the main section of the plunger and the shoe section `is made air tight by a ball and socket joint, or a gasket or anvother desired method.-

35 designates a blind air bore that extends dovvn through the stem 22 into the shoe section` of the plunger through the portion 30 and the neck 33 and may be extended down into the proper 34. l l

37 isan air lead pipe thatiis secured to plunger 22 by fixture 36 at the top of bore 35,'and connected by union lug 38 to pipe 39 that leads to the train pipe of 'the air brake s vsteni. In this manner, the train pipe air pressure may be maintained in the blind bore 35 so that in the event of a breakage of the neck 33, or the stem 22, the air brakes will i be set.

The head 42 may be of the split or divided type and includes thebase parts 40, which are provided with ears 41 through which clamping bolts or screws are fastened to secure the head rigidlyfto the upper end of the plunger.V The head 42 has a pin vbearing 43 which is adapted -to be suitably hushed to receive the resetting pin46. The head 42 Y is also .providediwith eai's 44 to which the lVhile it is 12o yieldable head 45 is pivoted.l Y preferred to have the head 45 yieldable yet it is not an absolute essential yto have the By making the head 45 yieldable one way material of the shoe (2f. e., by mounting it pivotally) should the 125 train be stopped while the plunger is on the ramp with the head 45 up above the cam 5 (a position itsometimes' assumes when the valve is all the way open) an attempt to reset the valve manually will not tend lto @nent "Warmte 'heten-"ot" made' yielding.' :and the plunger stopped Withthe upper end break oit-the head, as it will yield sulliciently topermitthe cam to assurneits normal potion'ilin; l: This turning iact releases sition.

The brakes having been set, as above described, and theftrain brought to astand- 4still or to a predetermined speed, the engineer can reset the valve b y pulling the' rod 13.

kFrom the foregoing description, talen in.

connection with. the accompanying drawings, 'it is thought the complete construction,

operation and advantagesof the invention [will be clear to those skilled in the art.

,l ln conclusion, attention is called to the fact that this-construction provides a train stopping apparatus of the double-action type which uses only a single plunger and asingle ramp; it provides a train stopping apparatus capable ofgiving both an opening and a reclosingzaction on the valve of an air brake system by means of a single plunger device and la s ingll ramp; it providesa train stopping apparatus whoseplunger always positively opens the vair valve on the upward movement and recloses the air valve on the- -downward movement when the reclosing act is desired; it provides a train stopping apparatus capable of giving a double-action when air duct, the construction being such that the breaking of any such moving part will allow the escape of' air from the train line and set vthe brakes. y
